    Ebola Virus Disease (EVD) also known as the Ebola hemorrhagic fever is a very deadly infectious disease to humankind. Therefore, a safer and complementary method of diagnosis is to employ the use of an expert system in order to initiate a platform for pre-clinical treatments, thus acting as a precursor to comprehensive medical diagnosis and treatments. This work presents a design and implementation of informatics software and a knowledge-based expert system for the diagnosis, and provision of recommendations on the appropriate type of recommended treatment to the Ebola Virus Disease (EVD). In this research an Ebola fuzzy informatics system was developed for the purpose of diagnosing and providing useful recommendations to the management of the EVD in West Africa and other affected regions of the world. It also acts as a supplementary resource in providing medical advice to individuals in Ebola – ravaged countries. This aim was achieved through the following objectives: (i) gathering of facts through the conduct of a comprehensive continental survey to determine the knowledge and perception level of the public about factors responsible for the transmission of the Ebola Virus Disease (ii) develop an informatics software based on information collated from health institutions on basic diagnosis of the Ebola Virus Disease-related symptoms (iii) adopting and marrying the knowledge of fuzzy logic and expert systems in developing the informatics software. Necessary requirements were collated from the review of existing expert systems, consultation of journals and articles, and internet sources. Online survey was conducted to determine the level at which individuals are aware of the factors responsible for the transmission of the Ebola Virus Disease (EVD). The expert system developed, was designed to use fuzzy logic as its inference mechanism along with a set of rules. A knowledge base was created to help provide diagnosis on the Ebola Virus Disease (EVD). The Root Sum Square (RSS) was adopted as a fuzzy inference method. The degree of participation of each input parameter was shown using the triangular membership function and the defuzzification technique used is the Center of Gravity (CoG). The resulting software produced a user-friendly desktop-based, Windows-based, application and the tools used were explained in the results section in three (3) separate phases. First, a comprehensive online survey was conducted over a period of about 3–9 months. 100 Participants participated in the survey on the perception and knowledge analysis of different individuals about Ebola Virus Disease (EVD) transmission factors. 31% of the participants didn't know that there is presently no cure for Ebola. 28% believed that there is presently a cure for Ebola. 43% agreed that Ebola is both air-borne and water-borne, while 33% disagreed, 24% do not know. 23% believed that insects and mosquitoes can help in transmitting the Ebola Virus Disease (EVD), while 30% were completely ignorant. We noticed that ignorance was a major limiting factor among some participants. Second, a test was conducted among 45 people. Results from a comprehensive testing of the Ebinformatics software by allowing users to operate and use the software, revealed that 60% of them were satisfied, while 16% were not satisfied with the software, while 24% were indifferent. 69% of the users were in agreement that Ebinformatics was supportive, 20% disagreed, while 11% were indifferent. 67% found the software easy to use, 13% disagreed, while 20% were indifferent.

    INFLUENCE OF ONLINE GAMBLING ADVERTISEMENTS ON UNDERGRADUATES OF A SELECTED NIGERIAN UNIVERSITY
    (KIU Interdisciplinary Journal of Humanities and Social Sciences, 2024) Oluyemi Abimbola Adekemi; Akinkoya Omoniyi Felix; Adeniyi Adeleke Olaoluwa; Bello Adesola Olufunmi
    This study investigated the influence of online gambling advertisements on undergraduates in Nigeria focusing on students of Olabisi Onabanjo University, Ago-Iwoye. Anchored on the propositions of social learning and cognizance theories, it adopted descriptive survey research design. The population of the study comprised of full-time students having 19,740 enrollments as at 2021/2022 academic years. The sample size was 395 respondents selected through simple random technique. Findings showed that peer pressure arising from colleagues’ winnings influenced the addictive gambling habits of respondents. Besides, online gambling also had negative economic consequence on the respondents because of the addictive nature of gambling which kept luring them to re-invest their winnings. The study equally found out that online gambling was more prominent among male students than females. Based on these findings, the study concluded that undergraduates in Olabisi Onabanjo University are exposed to online advertisements on betting which lure undergraduates to place more bets; and ultimately influences the betting habits of students. It therefore recommended that university management should include counseling against gambling and betting in the orientation programme of prospective students. Parents and guardians should also monitor and guard their children and wards against the addiction of online gambling.

    Learning through interaction: impact of interactive radio instructions in improving literacy skills of out-of-school children in IDP camps in Nigeria
    (Interactive Learning Environments, 2022-08-24) Oluyemi Abimbola Adekemi; Celestine Gever Verlumun; Talabi Felix Olajide; Talabi Joseph Moyinoluwa; Adefemi Victor Oluwole; Bello Samson Adedapo; Apuke Oberiri Destiny
    The goal of this study was to examine the effect of interactive radio instruction (IRI) in improving the literacy skills of out-of-school children in IDP camps in Nigeria. The study was a quasi-experiment involving 470 children who were out of school at the time of the study. The indices for measuring literacy skills included phonological skills, letter knowledge, oral comprehension and vocabulary skills. The result of the intervention showed that although all the children scored low regarding their literacy skills at pre-intervention, participants in the IRI group reported a significant improvement in their literacy skills after the intervention. A follow-up assessment was carried out after twelve months and the result showed stability in the literacy skills of participants in the IRI group while those in the control group did not improve in their literacy skills over time. Comparatively, IRI was found to be more efficient in improving literacy skills than a face-to-face learning environment. The implications of these results on learning have been highlighted.

    Perceptual Effect of Stereotypes in MTN Fastlink and Dettol Advertisements on Image of Female University Workers in Nigeria
    (NIU Journal of Social Sciences, 2024) Oluyemi Abimbola Adekemi; BELLO ADESOLA OLUFUNMI; AKINKOYA OMONIYI FELIX; ODIGIE JOSEPH DAYO
    This study investigated the perceptual effect of the advertisers’ strategies using stereotypical images of women to attract attention of consumers to their advertised products and services on the image of women in the work place using MTN (Fastlink) and Dettol Antiseptic advertisements as cases. The study specifically examined the extent of the gender portrayal in the selected advertisements; ascertained the audience interpretations of the gender stereotypes in the selected advertisements; and the perceptual effects of the stereotyped advertisements on female University workers in Ogun State. Survey method was adopted while questionnaire was used as instrument for data collection. A proportionate sample of 286 was drawn from staff members of three Universities in Ogun State while the convenience sampling technique was adopted for the administration of copies of questionnaire. Findings revealed that the selected advertisements portrayed women in an inferior context and showed that the advertisements capable of impacting negatively on the image of women in the workplace. Other findings showed female workers disagreeing to stereotypes in the selected advertisement affecting their personality while the audience generally perceived highly that female stereotypes can hamper managerial opportunities and positions for women. Hence, the study recommends that women should see themselves as talented individuals with unique skills, who can manage their affairs in the world with dignity and decorum. Females that feature in advertisements should reject roles that debase and dehumanize women folk. Advertisers should start representing women in the society positively and advocate for equity and women liberation in Nigerian society through advertisements.
